The Nikon D7100 looks a lot like the popular D7000 but has been completely overhauled internally. Interestingly, in a first for Nikon, the D7100 does not have an optical low-pass filter, promising optimal resolution from its 24MP CMOS sensor. The D7100 also gains a 51-point autofocus system, 1.3x crop mode for both stills and video capture, and multiple other upgrades, making it one of the most competitive cameras in its class, on specification alone.
